pistachio is a kind of leisure dried fruit, also known as "Wumingzi" and "Pistachio nuts", which is a kind of nut with a bleached shell. It is produced in Syria, Iraq, Iran and other countries, and is only cultivated in Xinjiang in China.
It is said that in the fifth century BC, during the Boshi War, the Persians relied on this kind of Ayurveda to make the army energetic and even win the battle. When Persian herders were nomadic, they had to carry enough pistachios to migrate far away.
Pistachio nuts contain vitamin E and so on, which has anti-aging effect and can enhance physical fitness. The kings of ancient Persian countries regarded them as "fairy fruits". In addition, it also has the effect of moistening intestines and detoxifying.
In addition, the landlord should pay attention to the fact that the green pistachio nuts are fresher than the yellow ones. Pistachios stored for too long should not be eaten again.
As a rare food in the world, pistachios are the favorite food of the Queen of Sheba. The Queen of Sheba once ordered that all pistachios produced in the territory she ruled belonged to herself and the royal family. This royal nut was imported by American traders in the 198s, mainly serving American citizens with Middle Eastern ancestry. About 5 years later, pistachios became a popular snack and were sold on vending machines. These imported nuts are dyed red, on the one hand to attract attention, and on the other hand to cover up the stains caused by traditional harvesting techniques.
The birth of California Happy Fruit Industry followed closely. In 1929, American botanist William E. Whitehouse spent six lonely months in Persia (today's Iran), collecting seeds and carefully selecting from piles of products to find the most outstanding quality pistachios. He returned to America with a sack full of seeds and weighing 2 pounds.
the following year, experimental planting was carried out in California (the desert-like climate makes it an ideal growing place). Because it takes seven to ten years for happy fruit trees to mature, it was not until 195 that the first successful happy fruit tree appeared in front of people. This variety is called Kerman, named after the famous carpet manufacturing city, and the seeds of pistachios are collected near the city. Since then, scientists have further strengthened Kerman by budding this variety with stronger primary taproot varieties.
Now, the idea of establishing happy fruit industry in California is gradually coming true. Rumors about this new crop spread, and in the 196s, the cultivation of pistachios spread throughout California. However, for these adventurous Californians, many problems related to this new crop remain a mystery.
after a long wait of seven to ten years, expecting their investment to be rewarded, they finally found that pistachio is a kind of crop that bears fruit every other year, that is, one year is fruitful and the next year the fruit withers. But it is precisely because of their diligent efforts and unremitting efforts that the pistachio industry has taken shape. Now, the state has become the second largest pistachio producing area in the world.
the first batch of 1.5 million pounds of commercial pistachio crops were picked in 1976, and the crops were produced on 4,35 hectares of land. Today, California has more than 96, hectares of pistachio plantations, and its output is 1 times higher than the first harvest.
in recent years, a new and fashionable food "pistachio" has appeared in the market. Its shape resembles ginkgo, and the green seed kernel is exposed from the crack after the peel cracks, which is sweet and loose when chewed.
Pistachio nuts are the fruits of deciduous trees of Uraceae, whose height is 1 meters, and they are long-lived trees, and their age is as long as 3～4O years. It blooms in May and bears fruit in September every year. Harvest when the peel is cracked and the green nuts are exposed. Its nut is a highly nutritious food, which contains carotene, vitamins E, C, B〓, B〓, nicotinic acid, egg quality, minerals and so on. The oil content of seed kernel is as high as 45? 1%, cold pressed oil can be used as high-grade brain oil and raw materials for cakes and artificial cheese. Pistachio nuts are nourishing and edible drugs, which are sweet and nontoxic, warm the kidney and spleen, benefit deficiency, regulate the middle energizer and smooth qi, and can treat neurasthenia, edema, anemia, malnutrition, chronic diarrhea and other diseases. "Pistachio" is named after its effect of "relieving depression with happiness".
Pistachio nuts have been used as dietary supplements in China for more than a thousand years. In the Tang Dynasty, there was a Persian descendant named Li Xun who wrote a book "Herbal Medicine of Haiyao", which included pistachios. He said, "In fact, if it looks like hazelnuts, the Persian family calls it pistachio." Because it came from the western regions, another pharmacist in the Tang Dynasty, Chen Zangqi, called it "Huzhenzi" in his book "Herbal Supplement". In the Yuan Dynasty, Hu Sihui, a physician, took its transliteration in his dietotherapy monograph "Eating and Eating" specially written for the emperor, which was called "Must Think and Answer". Today, Xinjiang minority areas, Arab and Islamic countries and Japan still call it "must think and answer".
Pistachio nuts originated in Turkey, and were artificially cultivated 3, years ago, and then spread from the Mediterranean to Afghanistan, the Near East and South Asia. It spread from Syria to Rome in the L century and to Britain in the 18th century. The United States developed late for nearly a hundred years, but it developed rapidly, and it was cultivated in California, Arizona, Texas and other States with great output. Therefore, most of the pistachios we see in food stores today are imported from abroad. However, it is also cultivated in Xinjiang and other places in China, but the output is not high. The prospect of developing pistachio planting in China will be very attractive.
